IMPROVEMENT IN LUBRICATOR FOR Loose WHEELS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern.- I

Be it known that I, SYLVANUS E. P nxnrfol' Mc- Keesporhin the county ofAlleghenyandState of Pennsylvania,have invented a new anduscful'Improvement in Construction of Loose \Vheels; and I. do herebydeclare the following to be a vfull, clear, and exact descriptionthereof, reference being had to the accompanying drawing making a partof this specification, in which- Figure 1 is a perspective view of' myimproved wheel, a-portion of the cap which covers the oil-chamher .beingbroken away, the better to show the construction of the latter;

Figure 2 is a section ot' the hub as formed by a plane passing throughat right angles to the axis; and q Figure 3 is a section through theline a: w, fig. 2.

Like letters of reference indicate like parts in each.

In the use of loose wheels for mechanical purposes, such aspulley-wheels, car-wheels, &c., considerable diificulty issometimesexperienced in keeping the wheels properly oiled.

For this purpose'whcels have been made which had an oil-chambcrin thehub or extending around it, to contain a supply of oil for the axle.

My improvement relates to this class of wheels, andc'onsists in makingthe oil-chamber or reservoir of an improved form, in connection with anoil-opening from at or near the smallest part of the chamber to the axisof the wheel.

To enable others skilled in the art to make and use my invention, I willproceed to describe the same withparticular reference to itsconstruction and use in wheels for coal-cars, as they are called, in thecoalmining sections of the country.

The casting of the wheel A is done in any of the ways known to the art,so as to give a tread,'a-, or rim, spokes b b, and a chambered hub, a,being the outside of the chamber, 0' the inside or axle-box, and a" theend made close in casting;

The chamber an, included between these sides, is made in casting, by theuse of a dry sand core; The chamber in is of the form shown, and,instead of extending entirely around the hub, is interrupted at onepoint by one of the spokes, b, which extends to the box 0', or-by asuitable diaphragm in lieu thereof.

On one side of this diaphragm the chamber in is narrow, say aboutone-half an inch wide, more or less, measured on the line of the radiusof the wheel which runs tllrouglrit, and thence extending around strikesthe diaphragm b, where it is, say, about two inches in width, more orless, similarly measured.

At or near the narrowest part of the chamber, an oil-opening, 0, extendsthrough the inner box 0' and supplies oil to the axle.

The outside of the chamber is closed by a cap, (I, which, suitablypacked if need be, is fastened on by bolts and nuts, 1, or inother-similar m The chamber is kept supplied with oil, from time totime, through an opening, s, which may be closed by a plug, 5', cap, orother like device. 7

But I do not wish to limit myself to the dimensions named for thechamber, nor to its use in coal-cars,

but include in my invention any chamber. in the hub of a loose wheelwhich chamber increases in width from one side of a diaphragm around tothe other side. r

In the use of chambered wheels, as heretofore constructed, I have foundtl lat-they commoi'ily'supply oil to the axles or hearings ,in too greatabundance and waste the oil.

I My improved wheel is, like them, a sclt-oiler, but it oils the axle orbearingonly at intervals. i

"When the car is in rapid motion the centrifugal forcetas itis called)tends to keep the oil clear of the slot c, and causes it to accumulateinthe larger part of the chamber, this result being further secured bythe eccentric form of the inner face of the 'outer shell As the carsmove slowly in stopping and starting, the oil, of course, flows to thelowest point, and during a portion of the revolution of the wheel -willset back in the narrowest part of the chamber against the diaphragm b,and a portion of it will then pass through the slot e and oil the axle.

I have found in practice that by the use of these devices the wheel willbe kept snfiiciently well oiled,

and that little or no oil will be wasted.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is--,

The chamber m east with and extending around through the hub, andincreasing in width. from one sideot' the diaphragm I)" tothe other, andwith an oil-opening, e, at or near the narrowest end of the chamber. 7 V
